` Application leg February 26, 15H5. Serial No. 10,809.

To ZZ zowm t may concern lle it known that we, GEORG OSCAR Win54, a subject of the German Emperor, residing at KleinSchmalkalden, in the Duchy of Gotha, Germany, manutan-tuner, and OTTo Pie/itin, a subject of the King of Wurttem hei-g. residing at Stuttgart, in the Kingdom ot' lVurtteini'Jerg, Germany, engineer, have,

invented certain new and useful Improvements in lllotonPlows, of which the followis a specification. This invention relates to motor. plows and more especially to a motor plow conneoted with a traine Carrying the plow.

shares is pivoted to a cra-nk arranged on the v 'i'aotion engine or motor oar, said Crank being adapted to he' rotated either by hand or by any suitable mechanism and, on being moved troni the horizontal position into an upright vertical position, lifting the front end of the. traine, the back end resting on an adjustable wheel.

According to the present invention a pair ot hell Crank levers are arranged at the lmet: end of the motor car. The levers are rigidly fastened to a hoi'izontal'shaft'ex tending" across the oar traine, and the ends ot their lower arms engage in horizontal slots near the middle part of the Atrame carrying the blades. Stops arranged on this traine between the slots and the ends of. the upper arms of the oeil crank levers serve to turnthose levers and to lift the fra-me, whenever they are moved toward and into` contact with these arms which, however, are free to follow the osoi lations of the frame long as this latter in its ,working position. n

The drawings anneied to this specification show the preiiei. 1'iorin of a motor plow according 'to the present invention.

Figure lis a side elevation of the motor plow showing itin Working position (in.

Figs. 3 to 5 are side elevations of the inotor ear and plowshares4 in n 'orking'psition (Fig. 3), in the course of lifting the plowshaies (Fig. 4), and in the uppermost position of the piowshare freine.

Reiierring to the drawings, A is the trac- .tion engine or motor car, B is the loar frame, C is the frame carrying the plowshares o1' blades, E are twoorank arms rigidly fixed on a cross shaft D and pivotall'y connected to the front ends of the frame C. The shaft l) and crank arms E are adapted to be 1'0- tated in the direction of the arrow.

it the rear end of the .motor ear frame the Cross shaft l? is located, said shaft carry ing a pair oi' bell crank levers G lvl. The

f lower arms lvl of the hell crank levers enupper arms G of the hell crank levers are provided with sidesiollers J lying infront of theslotted shoulders P.

. When the shaft l) is rotated in the dire@ tion of the arrow (Fig. 4l), the onank arms E lined to it will lift the front end ojtf he plowshareframe C (Fig. si), the 'adjustable Wheel L carrying the tail end ot said frame still resting on the ground. As soon, however, as the front edges K oit the .shoulders P have come in Contact with the rollers J -o the upperJ arms Gr of the hell crank levers, the crankarmsdrawing the frame C and shoulders P forward, the hell crank levers G M will he turned in the saine direc tion and their arms M will lift the rear end o the trarne C 'from the ground and the plowshares out of the furrow, the frame C tinaliy assuming the position shown in Fig. 5. 0n further rotating in the direction of the arrow beyond the horizontal position shown in Fig. 5 the crank arms E willallow the hell crank levers (if M to return to theii` initial position and the frame C to be lowered again into` working position,

^ motor car, a plowsharefraine attached to said car, and having horizontal guides, means for pulling said fra-me toward the car, a pair of rlgidly connected bell crank levers pivoted to the rear end of said car,

the lower arms` of said levers engaging in the horizontal guides on the plowshare frame, and stops on said frame between the lower and the upper arms of said bell crank levers. v

3. In a motor plow, in combination, a mot-or car, a crankshaft extending across said car, means for rotating said shaft, a plowshare-rame attached to said car and having horizontal guides, the front end of l said: :traine being Vpivoted to the cranks of said leverslengaging irrthe horizontal guides saidv crank shaft, and a. pair of levers rigidly connected with each other and pivoted to the rear end of saidcar, the `free ends of on the plowshare france.`

4. In a mot-or plow, in combination, a inotor car, a crank shaft extending across said car, means, for rotating said shaft, a

plowshare-fra1ne attached tosaid car, and

having horizontal guides, the front end of said frame being'pivoted to the cranks of said crank shaft, a pair or rigidly connected bell crank levers -pivoted tothe rear end of said car, the-lower arms` of-said levers engaging in .the horizontal guides on the plowshare frame, and stops on said frame between the lower and the upper arms of said bell crank levers.

5. In a motor plow, `in combination, a motor car, a crank shaft extending across said car, means for rotating said shaft, a plowshare-frame attached to said car, and having horizontal guides, the front end of said frame being pivoted to the cranks of said crank shaft, a shaft extending across the rear end of said car, a pair of bell crank levers xed. to said shaft, the lower arms of Said levers engaging in the horizontal guides on the plowshare-.fraine, and stops on sai frame in front of said guides, said stops being adapted to come in contact with the upper arms of said bell crank levers.

6. In a motor plow, in combination, a motor car, a crank shaft extending across said car, means for rotating said shaft, a

:sel

plowshare-frame attached to said car, thefront end of said frame being pivoted to the cranks of said crank shaft, a. shaft extending across the' rear end of said car, a pair of bell crank levers fixed to said shaft, and vertical shoulders on the plowshare-itrannn having horizontal slots formed tliereilir-.the lower. arms of the bell crank levers engaging'in said slots and the front edges of said shoulders being adapted t'o Icome in contact with the'upper' arms of said bell crankl levers.

n witness whereof Wehave hereuntoset our hands in the presence of witnesses.
